Development of a yogurt recipe using Clitoria ternatea

   A recipe for the production of yoghurts with the introduction of powder and infusion of ternate clitoria of different concentrations has been developed; quality control of the finished products for organoleptic and physicochemical indicators has been carried out.

   The goal of the research was to develop a recipe for yoghurt with the introduction of different concentrations of infusion and powder of ternate clitoria, to evaluate the quality components of the finished products.

   The studies were carried out in the laboratory of the Department of Biotechnology and Food Products of the Ural State Agrarian University. Pasteurized drinking milk with a fat content of 3.2 %, a complex starter culture consisting of Streptococcus thermophilus, Lactobacillus delbrueckii (variety bulgaricus), Lactobacillus casei, infusion and powder of ternate clitoria, Jerusalem artichoke syrup, and vanillin were used for the production of yoghurts. Temperature control of the samples was carried out in a Galaxy GL2696 yoghurt maker for 10 hours. A total of 7 samples were obtained, 6 of which were enriched with powder and infusion of ternate clitoria, and one sample was a control one. Sample No. 2, made with the addition of ternate clitoria powder weighing 2 g, was recognized as the best according to the results of organoleptic studies. The yogurt had a pleasant fruity taste and smell, a uniform consistency, and a light lilac color. Yogurts made with the addition of ternate clitoria infusion had a layered consistency, a not entirely pleasant herbaceous taste, and some samples were characterized by a slight metallic taste. The results of physicochemical studies indicated a slight increase in the mass fraction of fat, protein, and acidity when adding ternate clitoria powder. On the contrary, ternate clitoria infusion affected a decrease in the content of fat, protein, and acidity in the finished samples.

   Conclusions. It is recommended to use yogurt with the addition of 2 g of ternate clitoria powder in the diet of people of different age groups.
